T0 (LI/Z wir/0m it muy cori/cern:

Be it known that I, JOHN O. BARR, a citi- Zen of the United States,residing at Tacoma, in the county of Iierce and State of Washington,have invented new and useful Improve` ments in Circular Oonveyers forShips, of which the following is a specification.

My invention relates to improvements in the construction of the decks ofships, barges and the like and has for its object to provide a deck ordecks of turntable or turret form to allowA the easy, quick and completeloading and unloading of a ship,- to provide separate compartments forthe reception of different kinds of freight destined to differentpoints, and to allow the loading and unloading of each compartment oneach deck without disturbing the remainder of the cargo.

To the accomplishment of the foregoing and such other objects ashereinafter appear, the invention consists in the features andcombination of parts hereinafter particularly described and then soughtto be clearly defined by the claims, reference being made to theaccompanying drawing forming a part hereof and in which Figure l is atop plan view of a portion of a ship or barge equipped with my improved.form of deck and Fig. 2 is a vertical section of a ship having its lowerdecks constructed according to my invention.

In the drawing, the number l represents the sides, 2 the bottom, 3 thetop deck and 4 the lower deck of a ship. Suitably mounted on these decksare supplemental decks or floors 5 of a turret or turntable form,preferably circular and in diameter approximately equaling the width ofthe deck. As shown these supplemental decks or turrets are provided withcentral bearings 6 surrounding vertical shafts 7 and are rotated thereonby any suitable means. Antifriction rollers S are provided between thesupplemental deck or turret and the deck proper. The circular floors ordecks 5 are preferably surrounded or inclosed by vertical walls 9 andthe inclosed space is divided into separate compartments 10 by theradial upright walls or partitions 1 1 extending inwardly from the outerwalls 9. IIatches 12 are provided in each of the decks 4 and also in thesupplemental decks 5 to allow the lowest turret to be filled first. Inorder to have access to each separate compartment on each deck to allowthe loading or unloading of the freight in separate lots or shipmentsconsigned to different ports without disturbing any other portion of thecargo, hatches 13 are provided to one side of the decks'4 in the anglesleft between the turrets. The compartments 10 are provided with doors oropenings 14 in their outer walls which gives access to the angle spaces.

The entire supplemental deck or floor 5 and its inclosing wall 9 may besurrounded by wall 15 affording additionalprotection and strength to theconstruction. Openings 16 are provided in such wall 15 for the removalof freight.

For the shipment of coal, ores, grain, sand or other granularsubstances, the compartments 10 may be constructed with iioors 17inclined toward the doors or openings 14 in the side walls of the turretwhich give communication to the side hatches 13. By this constructionthe contents of the compartment are caused -to gravitate toward thehatch when the door is opened and thereby eliminate the necessity ofshoveling. l

In loading a vessel equipped with my invention the compartments in thelowest deck are first filled, the turret being rotated to bring thecompartments separately under the hatches 12 through which the freightis lowered so that the compartments may be successivelyfilled. Then thedeck next above is loaded and so on. Vhen the outer walls 9 of thecompartments are provided with doors or openings the loading ispreferably done by lowering the shipments through the side hatches 13and storing them in the compartments through the doors thereto. Thecircular floor is rotated to bring each compartment in line with open-ling and thus they are all filled. By this construction any compartmentor any deck can be filled with freight or unloaded without disturbingthe freight in the other compartments. This does away with an immenseamount of labor and annoyance and allows quick access to any part of thecargo without sacrificing any storage space.

This is a division of the application filed January 16, 1906, Serial No.296,418.

Having described my invention and set forth its merits, what I- claimis 1. In a freight-carrying ship, the combination with a deck, of asupplemental freight supporting flooring or turret capable of rotationfor transferring freight from one point to another in the ship, and ahatchway in the IOO IIO

deck above the rotatable flooring for loading and unloading freight toand from said movable flooring through said hatchway.

` 2. ln a freight-carrying ship, a rotatable floor or turret fortransferring freight from one point to another in the ship, and separatefreight compartments carried by said floor, constructed to permit theloading and unloading of freight to and from one compartment withoutdisturbing the freight in the other compartments.

3. In a ship, a rotatable deck formed with compartments, saidcompartments having an inclined iloor.

4.' In a ship, a rotatable deck formed with compartments, saidcompartments havinga floor inclined outwardly from the center.

5. In a freight-carrying ship, a rotatable flooring or deckfor-transferring freight from one point to another in the ship, a wallinclosing said deck, and partitions extending inwardly from said wall toform separate compartments, said partitions terminating back from thecentral portion of the deck to form a space through which access may behad lto the compartments from the central portion of the deck.

6. In a ship, the combination with the decks, of supplemental deckscapable of ro tation and hatches in said decks and supplemental decksfor access from one deck to the deck neXt below.

7. ln a ship, the combination with the decks, of rotary turrets orfloors, walls inclosing said rotary turrets or floors and doors in saidwalls for access to said turrets.

8. In a freight-carrying ship, the combination with a deck, of asupplemental circular deck or flooring rotatably mounted thereon fortransferring freight from one point to another in the ship, and rollersdisposed between said deck and supplemental deck.

9. In a ship, the combination with the decks, of a series of circularsfloors or turrets rotatably mounted upon said decks, walls inclosingsaid turrets, and doors in said walls communicating with the spacebetween said turrets.

10. In a ship, the combination with the decks, of a series of circularfloors or turrets rotatably mounted upon said decks, walls inclosingsaid turrets, partitions extending inwardly from said walls formingcompartments, and doors in said walls to each compartment, saidcompartments having floors inclined toward said doors.

1l. In a ship, the combination with the decks, of a rotatable circularfloor or turret to each deck, an upright wall to the floor or turretformed with openings for access to the space inclosed by the wall,vertical partitions extending inwardly from the wall formingcompartments to which access is had through the openings in thewall,andV hatchways in the decks and turrets for access from thecompartments of one turret or floor to the compartments of the turret orfloor neXt below.

12. In a ship, the combination with the decks, of a series of rotatablecircular floors or turrets oneach'deck, Vertical walls to each iloor orturret, upright partitions eX- tending inwardly from said walls formingcompartments, openings in said walls and hatchways in said decks locatedin the angular spaces between said circular floors or turrets wherebyaccess is had to each one of vsaid compartments through said openings inthe walls.

ln testimony whereof I affix my signature in presence of two witnesses.
